This document discusses creating linear inequalities in one variable. It begins by introducing inequalities and their symbols like >, <, ≥, ≤, and ≠. It then discusses key concepts such as solving inequalities is similar to solving equations, but multiplying or dividing by a negative number requires reversing the inequality symbol. Examples are provided of creating inequalities from context by identifying known and unknown quantities. The document concludes with a guided practice problem where students are walked through setting up and solving an inequality based on a word problem.
